Hey Spooky...
Unless the water pump is leaking coolant or making a noise, I would not replace the water just because I'm replacing the fan clutch.
Regarding the water pump... remember to maintain fresh coolant per recommended maintenance periods. The coolant helps to lubricate the water pump, which helps prevent early water pump shaft failure.
Has the fan clutch failed?
Gnarls.
Ok, my fan is starting to fail. Don't want it to fAil when I don't have time to fix. So I am replacing it. Can't be breaking down on the way to school or work.
